Appueation ined August is, 1917. serial No. 186,277. f

similar to Fig. 15 but showing a later con.

dition of the apparatus, and Fig. 1 8 is a view in vsection along the line 18-18 of Fig. 16.

Referring to the drawings and particularly to Figs. 1 and 2, 20 represents a base plate which may be constructed of wood,

metal or any other suitable material. This base plate is provided with a central groove 21 of a shape and size corresponding to the shape and size of one-half ofthe wrapper which is to be formed on the apparatus. A mandrel 22 is adapted to coperate with the groove and this mandrel has the shape and dimensions of the interior of the wrapper which is to be formed thereon, except that it is a triiie shorter. The mandrel is provided with an extension 23 pivote'd to lugs 2st-extending upwardly from a shelf 25 projecting from the end ef the base plate 20. 1n order to place the sheet of'material of which the wrapper is to be formed in the right position upon the base plate. the latter is provided with guides 26 atv its sides and other guides 27 attached to its ends.

n using the apparatus to form a battery wrapper the shelf 25 is placed toward the operator and the mandrel is turned intothe position shown in Fig. 1. A vsheetl of material Q8 of the required size is then laid upon theV base plate and the mandrel moved into the position shown in Fig. whereupon the paper will be drawn .into a. position substantially like that shown in this figure.

The operator then, takes a str ipof tape 29 which has been vcoated with adhesive and nioistened and places it upon the top of the mandrel with one end 30 extending overthe free end of the mandrel as shown most clearlyin Fig. 4. The gummed side of the tape is exposed and to the end portion of the tape is attaehed an oval bottom 31 which may be of cardboard or any other desired material. Since the mandrel is of slightly less length than the wrapper formed there 011,' the material wiil project over the free end of the mandrel forming a recess of depth just Sufiicient to receive the bottom.

per edges and into these recesses are fitted plates 51, attached to the top of the guides 49 by screws 52; Since the ormers are intended to slide back and forthv on the base plate, they should beprovided with grooves 53 on their under surfaces to permit them to move over the stops 44 projecting from the upper surface of the base plate. Each former has attached to its under 54 to which is pivoted a link 55, the other end of which is pivoted to one end of a bellcrank' lever 56 mounted in a bracket 57 eX- tending upwardly `from' the supporting plate 40. There isa. link and a bell crank lever for eachformer and the adjacent ends of the levers are connected by links 58 to a fork 59 attached to the end of an operating rod 60 which may extend beneath the ap paratus to a pedal not shown) by Which the rod may be actuated. In order to hold the foi-mers in separated position, and to restore them to this position after each operation, a spring 6l may be provided. e stop 6l projecting above the base plate n? f beprovided for limiting the outward iovement of the tormers. The meeting edges of the Eormers are provided with recesses 62 hav ing a curvature like that of the corresponding -parts of the depression inthe base plate so that When these derniers brought into operation, theiv riii foid the material over the edges of the mandi-el 6B. This is ized to ings 64 which may be integral wi M attached to the bed plate by screens 65.1'

-:e free end of the mandrel may be covered by a. pad 66 of felt or other suitable material to aid in pressing the tape and the bottom of the Wrapper together.

-On the other side of the base plate and in position to engage 'the free end of the mandrelwhen it is placed in the depression in the base plate is apresser 67 which may bemounted between lugs 68 attached toa plate 69Which in' turn may be attached to the bed plate by screws 70. The presserv 67 is formed With a depending sector 7l extending .through an aperture 7:2 in the bedfplate. The geared surface of the sector is engaged by av gear 573 mounted on a shaft 74 between bearin s 75 ezrtendinvu Wardly vfrom .the

g s P supporting. plate 40. Attached to'A the gear or to Ythe shaft upon Which it is mounted isy va crank arm 76, at the outer end of which is a fork'77 attached tothe upper end ofthe rod 7S which extends downwardly to a pedal (not shown) by Which the gear may be actuated to bring the presser 67 into engagement with the end of the mandrel. In order to retain the presser innormal position outv ofengagement ywith the end of the mandrel, a spring 79 is placed around the rod 78 and engages the under side offthelfork77 and at its other end is held in place by a cylindricalcap 80: attached to the underside of' 66 the supporting plate 40 and vhaving at its side a lug `taching the edges of away from vthe bottom of theA mandrel. The' f 15. The sheet of material out ffwhich the y sides of the Wrapper are to befformed is laid. upon the base plate as' indi'catedat 45 in, A Fig. 14 andis properly" positioned bythe y75 guides 43 and 44. The mandrel, which at'1 the beginningl of the operationv should'` oc cupy the position shown" in-'Fig. 13'is then.k swung over and 4dropped into Lthe depression 42 carrying the material 'att/er'itfand` causing 8o the edges of the material "to assuni'ea'n 'up/7 right position corresponding in general` to the condition shown inFig. 2.' A strip'of gummed tape is then laid uponftheftop of the mandrel With its endV placed" over the free end of the mandrel. As in "th'ecase of the simple apparatus shown n Figs. l and 2, themandrel of the present embodiment is formed of a slightly lesser length than the desired article so that the material forming the sides of the latter projects slightly be"-H yond the end of the mandrel forming al space adapted to receive thebottom of they wrapf i per Which is stuckto theend ofthe tape and` then'retained in place by the presserl 67 which is actuated by thepedal l'connected to the rodv 7 S.v The pedal connected to'therod 60 is next actuated to Vdrawdown this rod and through the links and'bell crank leyer'sf, to cause the formers 48 to approachA each' other and fold the free 'edgescf the material down on top of the mandrel and hence intoV engagement With the gummed 'tapewhich hasV previously been" laid alongpfthel upper side of thev mandrel. The 'operation of at:

the paper to this gummed tape may, if necessary,'be aided byI the operator who presses themaipon the tape. The space between' the "ends of the formers when they are in operative position, will be suiicient to permitthe' operator tov fold the tape overthe-edgeofl the rvrappv'er,` and along the upper vlside of the''nieetingy edges so that these edges arel securelylunited before the; former's are WithdraWnffBotlg-L 1,157(
